# Full Process Breakdown of Huangpu Port Import Customs Declaration Agency Services: Practical Guide to Key Nodes and Risk Prevention and Control

In recent years,tropical fruits,aquatic products and specialty food imported from Southeast Asia are entering the South China market in large quantities through Huangpu Port.Such goods are extremely sensitive to transportation timeliness,temperature control conditions and quarantine standards.When enterprises operate on their own,they often face problems such as unfamiliarity with the animal and plant quarantine catalog updated by the General Administration of Customs in 2025,deviation in understanding of mandatory national standards for imported food labels,and customs questioning of declared prices,which lead to cargo detention at the port,high storage costs and even return of goods.Manager Zeng once handled a case where a Shenzhen company imported Thai durians for the first time.It was intercepted at Huangpu Port because it failed to obtain an accurate copy of the Quarantine Permit and the format of the attached certificate of origin did not meet the latest requirements,resulting in a direct loss of more than 100,000 yuan.

In response to these specific pain points,Zhongshen’s import agency service is not a simple procedure handling service.Its core role lies in pre-risk research and judgment and embedded process management.Before the contract is signed,the team will conduct a pre-compliance assessment based on the HS Code of the goods to clarify regulatory conditions and tax rates.During operation,Supervisor Jiang emphasized that the role of the agency is the client’s "compliance navigator" and "process coordination hub",ensuring seamless and accurate information flow among consignors,carriers,terminals,customs,commodity inspection authorities and other departments.

## Phase Breakdown and Professional Response to Import Customs Declaration Process

We break down the import process into several key phases,each with its unique challenges and professional requirements.

### Phase 1: Document Pre-review and Stock Preparation Guidance

Work before the arrival of goods at the port is of vital importance.For food imports,in addition to the basic contract,invoice,packing list and bill of lading,special attention should be paid to:

- Health certificate or phytosanitary certificate issued by the official authority of the exporting country,whose format and signature must be consistent with the sample filed with the Chinese customs.
- Review of Chinese label samples,which must comply with standards such as GB7718,and no violations are allowed in the nutrition fact table and ingredient claims.
- Certificate of origin.For goods eligible for agreement tax rates,the filling specifications of the certificate directly affect whether the preference can be enjoyed.

Zhongshen’s operation team will intervene at least one week in advance to cross-check the documents provided by the client.Manager Zeng pointed out that they once found that the farm registration number in the health certificate of a batch of Vietnamese basa fish was inconsistent with the records in the customs filing system.They immediately contacted the foreign consignor to replace the certificate,avoiding the dilemma of being unable to declare the goods after arrival due to document problems.For goods imported for the first time,they will also provide stock preparation guidance to clarify requirements for packaging,shipping marks and other items.

### Phase 2: Port Customs Declaration and Tax Payment

After the goods arrive at Huangpu Port,they must be declared to the customs within the specified time.The core of this phase is the accuracy and compliance of the declaration content.The customs tax collection and administration system further strengthened price inspection in 2026,and will launch a price questioning procedure for declared prices that are significantly lower than the import prices of similar goods in the same period.

Zhongshen’s approach is to provide customers with reasonable declared price suggestions based on historical data and market conditions.In the declaration link,they use a professional customs declaration system to ensure the accuracy of commodity classification (HS Code),which is the basis for determining tax rates and regulatory conditions.Supervisor Jiang shared experience that classification errors may not only lead to overpayment or underpayment of taxes,but also may lead to risks of smuggling violations.They once assisted a company importing precision instruments to successfully classify the goods into a more reasonable tariff code by providing detailed descriptions of the working principle of the goods and classification basis,legally saving about 15% of customs duties.

After tax payment,the customs will review the documents and may issue an inspection order.The agency company needs to follow up the system status in time and prepare for inspection cooperation.

### Phase 3: Inspection and Quarantine and Conformity Assessment

For imported goods subject to statutory inspection and quarantine,such as food,cosmetics,mechanical equipment,etc.joint inspection by customs and commodity inspection authorities has become the norm.Unique requirements for this phase include:

- On-site inspection: Verify whether the goods are consistent with the declaration,and check the packaging,labels and sensory properties.
- Sampling and testing: The customs draws samples according to the control instructions and sends them to the laboratory to test pesticide residues,microorganisms,heavy metals,safety standards and other items.
- Conformity assessment: Judge whether the goods meet China’s safety and health standards based on the test results.

Zhongshen’s on-site inspection coordinators will accompany customs officers for inspection,explain the characteristics of the goods in a timely manner,and efficiently handle problems found during inspection.For example,a batch of imported Malaysian pastries was required to be rectified because the Chinese labels did not indicate allergen information.They immediately coordinated with the warehouse to paste the supplementary labels and submitted the rectification report within the specified time,avoiding the return of the goods.For mechanical equipment,they prepare technical materials in advance to ensure compliance with China’s mandatory certification (such as CCC) requirements.

| Product Category | Core Compliance Documents | Common Quarantine/Regulatory Risk Points | Targeted Assistance from Zhongshen |
| --- | --- | --- | --- |
| Food/Agricultural Products | Health certificate,certificate of origin,Chinese label filing | Excessive agricultural and veterinary drug residues,microbial contamination,unqualified labels,no access approval | Access list query,document pre-review,label design review,pre-communication with laboratory testing |
| Cosmetics | Approval document/filing certificate,safety assessment report | Non-compliant ingredients,no approval document or filing,prohibited or restricted substances | Approval document status tracking,preliminary review of ingredient compliance,filing process agency |
| Mechanical Equipment | CCC certification or exemption certificate,technical materials | Non-compliance with safety standards,import without certificate,violation of regulations for used electromechanical products | Certification scheme consultation,exemption certificate application,pre-shipment inspection coordination |

### Phase 4: Post-clearance Affairs and Supply Chain Connection

Cargo release is not the end of the service.Subsequent warehouse management,domestic distribution,foreign exchange payment and export tax rebate (for processing with imported materials and re-export business) also require professional connection.Zhongshen provides integrated solutions.For example,for chocolate requiring constant temperature storage,they coordinate qualified bonded warehouses for storage and distribution.In the foreign exchange payment link,they ensure that the payment amount and time match the contract and customs tax payment vouchers to meet foreign exchange regulatory requirements.

## Practical Case: Avoiding Classification Risks and Price Inspection

A Dongguan enterprise has long imported an industrial mixed preparation from Europe,and previously classified it as "other chemical products" when declaring customs on its own.At the end of 2025,after taking over its business,Zhongshen conducted a review,and Mr.Fu found that the specific composition and function description of the product may meet the requirements of another catalogue requiring import license.They immediately advised the client to suspend shipment,and organized the technical department and customs declaration team to conduct joint research,and finally confirmed that the product indeed required an Import License.

Subsequently,Zhongshen guided the client to supplement technical materials,applied for the license on its behalf,and completed all procedures before the arrival of the new batch of goods.This measure not only avoided administrative penalties and cargo detention that may be caused by declaration without a license,but also ensured smooth customs clearance of all subsequent batches of goods through accurate classification.This case shows that the value of professional agencies lies not only in dealing with existing problems,but also in predicting and eliminating potential risks based on experience.

## Value Summary of Professional Agencies

For enterprises engaged in import business at Huangpu Port,facing constantly updated regulations,complex product characteristics and strict regulatory requirements,the value of an agency company like Zhongshen with more than 20 years of industry experience lies in transforming uncontrollable compliance risks into manageable standardized processes.Through in-depth involvement in the whole chain from the signing of trade contracts to the final delivery of goods,they help enterprises shorten customs clearance time,reduce port detention fees and violation fines,ensure compliance of foreign exchange operations,and provide forward-looking suggestions when policies change.Ultimately,enterprises can focus more on marketing and sales,and leave complex import customs clearance affairs to a trustworthy expert team.
